137351-05-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137351-05-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,5 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137351-05:
(8*1)+(7*3)+(6*7)+(5*3)+(4*5)+(3*1)+(2*0)+(1*5)=114
114 % 10 = 4
So 137351-05-4 is a valid CAS Registry Number.

, p. 4799 - 4800 (2007/10/02)
N-Aryl-azetidine-3-acetic acids are converted to pyrrolidinones when treated with oxalyl chloride.The intramolecular cyclisation-N-dealkylation reaction occurs via an azabicyclic intermediate.N-Aryl-azetidine-3-acetic acids are prepared from N-aryl-3-(chl
